Anton Khirnov	3889dfde9c	dca: Move the downmix request check outside the loop	8 years ago
Luca Barbato	5352802da8	dca: Account for lfe when checking for the channel count Bug-Id: 1037 CC: libav-stable@libav.org	8 years ago
Anton Khirnov	6a9e331d79	dcadec: remove extra indirection num_core_channels is always equal to s->audio_header.prim_channels, neither one of those variables ever get changed. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	8 years ago
Luca Barbato	a46a4f722d	dca: Refactor dca_filter_channels() a little Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	8 years ago
Luca Barbato	e245d4f45c	dca: Validate the channel map Having a mismatch between the number of channels in the stream and those in the channel map will lead to a segfault or worse. Bug-Id: 1016 CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	8 years ago
foo86	d1f558b362	avcodec/dca: require checked bitstream reader Remove half-working attempt at supporting unchecked bitstream reader by always copying input data into intermediate buffer with large amount of padding at the end. Convert LBR decoder to checked bitstream reader. Convert dcadec_decode_frame() to parse input data directly if possible. Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
foo86	801dbf0269	avcodec/dca: simplify 'residual ok' flag tracking Move this from separate structure field to a packet flag. Behavior should be equivalent, except that residual flag is now properly cleared when packet has no core frame at all. Also print a message when forcing recovery mode due to invalid residual to make debugging easier. Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
foo86	39f7620d76	avcodec/dca: don't set initial sample_fmt Valid sample_fmt will be set by dcadec_decode_frame() based on stream type. Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago

foo86	4608996772	avcodec/dca: remove old decoder Remove all files and functions which are not going to be reused, and disable all functions and FATE tests temporarily which will be.	9 years ago
Hendrik Leppkes	51da00e24c	dca: adjust decoding of the XBR extension for integer core decoding	9 years ago
Alexandra Hájková	40d9496773	dca: use defines for subband related constants Signed-off-by: Janne Grunau <janne-libav@jannau.net>	9 years ago
Alexandra Hájková	2008f76054	dca: remove unused decode_hf function and quant_d tables They were superseded with their integer equivalents. Rename integer decode_hf to decode_hf.	9 years ago
Alexandra Hájková	aebf07075f	dca: change the core to work with integer coefficients. The DCA core decoder converts integer coefficients read from the bitstream to floats just after reading them (along with dequantization). All the other steps of the audio reconstruction are done with floats which makes the output for the DTS lossless extension (XLL) actually lossy. This patch changes the DCA core to work with integer coefficients until QMF. At this point the integer coefficients are converted to floats. The coefficients for the LFE channel (lfe_data) are not touched. This is the first step for the really lossless XLL decoding.	9 years ago
Anton Khirnov	2c6811397b	lavc: add profiles to AVCodecDescriptor The profiles are a property of the codec, so it makes sense to export them through AVCodecDescriptors, not just the codec implementations.	9 years ago
Clément Bœsch	fb99ef0bd3	avcodec: use AV_OPT_TYPE_BOOL in a bunch of places	9 years ago
Tim Walker	c12c085be7	dcadec: Do not check for overreads in auxiliary data The auxiliary data length field is not reliable, and incorrect overread errors could be returned for valid, real-world bitstreams. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
Alexandra Khirnova	58b42345b3	dcadec: reorganise context data place primary audio coding header data into DCAAudioHeader structure to make DCAContext clearer and move channel related data to DCAChan structure to make them easier to use by extensions Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
